Top Tech Startups in United States in 2027

HolmesAITM is an AI-native procurement intelligence platform built for teams that need to know what things should cost before they negotiate, not after.Most procurement technology digitizes the process. Holmes changes the inputs. Our platform combines a proprietary supplier graph with a large base of verified cost data points, then applies a 36-check rate intelligence framework and a 30-check quality framework to tell you where your spend is competitive, where it is not, and what to do about it.We built Holmes on an Outside-In approach. No supplier interaction, no fees, and every score traces back to a source URL. That means the intelligence you act on is independent, auditable, and defensible in front of a CFO or an executive team.What Holmes does:- Turns fragmented spend data into a clear view of categories, suppliers, and savings potential- Extracts and evaluates contract terms so obligations and risk are visible, not buried- Monitors supplier risk and performance continuously rather than at annual review- Runs sourcing events end to end, with AI agents that support the negotiation itself- Benchmarks every supplier against a Value Matrix of Value Leaders, Premium Incumbents, Converging Middle, and Value TrapsProcurement and finance teams use Holmes to find margin that traditional benchmarking misses and to move on it faster.Learn more at holmesops.ai

Callab AI builds AI voice and text agents for enterprise contact centers. We help companies automate customer conversations while keeping the telephony, CRM systems, and workflows they already rely on. Many contact centers run on established on-premises phone systems. Bringing AI to those environments is an infrastructure challenge as much as a modeling challenge. Our SIP-native telephony stack connects directly to systems such as Cisco CUCM, Avaya, and Mitel, so customers can deploy AI agents without replacing their phone infrastructure. Our platform lets teams build agents around their knowledge and business rules, connect them to tools that complete customer tasks, and supervise conversations in real time. When a conversation needs human judgment, a team member can take over with the context preserved. Use cases include customer support, call routing, appointment scheduling, lead qualification, and outbound campaigns. Backed by Y Combinator, We serve customers across three continents and are expanding in the US. Our work spans enterprise software, AI, and the telecom infrastructure that makes reliable customer service possible. We're building the next generation of contact-center automation. Explore our open roles to help bring it to more businesses.
